Heading south of the scorched intersection, you are welcomed by cool,
damp, but increasingly putrid air.  The air here rapidly turns to the smell
of rotting flesh and other things you do not want to think about.  Even the
strongest stomach would be tested to retain its contents.  Walking corpses
and other foul demon spawn make their way along the hallway making sure
their underground keep is free of invaders.
